I've got a 224 GB reiserfs partition on that. After 8 days uptime, it doesn't seem to have blown up yet. However I don't stress it heavily - just a nightly rsync or two which does a lot of reading and writing, and I export my music collection on it via NFS, which is a low level of read activity. I mirror the RAID to an external firewire drive nightly for backup, since I don't trust it 100% either, yet. I'd also be interested to know if there are known problems with software RAID5 in 2.6. Hope that helps, Torrey Hoffman thoffman@arnor.net On Wed, 2003-10-08 at 15:43, Måns Rullgård wrote: > Is software RAID5 stable in Linux 2.6.0-test7?
